You generally cannot change the color of the natural stone, such as making granite countertops darker or lighter. Some people claim that certain chemicals will lighten or darken granite, but those will damage the stone and not provide uniform, expected results, so it’s better not to try. Similarly, some people ask whether they can stain over granite. Granite is beloved for its stain-resistant finish, so you probably won’t get the best outcome if you try to stain over granite to make it darker.

Instead, consider honing, painting, or applying another material over the top of the granite to make it appear darker.

A water-based, low- or no-VOC sealer is typically a good choice for marble countertops. Choose a sealant that is certified safe for contact with food when applying to kitchen countertops. For high-traffic areas, look for formulas that have heat-resistant and acid-resistant features. While there are economical and convenient spray-on sealers, they don’t coat the surface as effectively as the ones you apply with a pad or brush. 

Avoid using abrasive cleansing powders on natural stone, as these products could damage the porous material. Using bleach is also a poor idea because of the porosity of the stone. Avoid using a scrub brush with metal bristles, as they could scratch the stone. If you know who manufactured your stone or who installed the fireplace, you may want to contact that entity for any advice on cleaning it safely.

How long it takes to complete stone restoration work will vary from home to home and project to project. Overall, a professional can complete a one-room project in one to two days. When vetting your local contractors, be sure to ask them how long they think the project will take to factor in any that could speed up or prolong the completion of the project.
